[REQUEST]recommendations on some Jpop/Jrock male artists/bands?

[Chiharo]

Ooh,ok,guys!
I'll try to take a look at everything you recommended!
So thank you all for recommendations!Because I'm so lost without them xD!

Now I'm into KAT-TUN and UVERworld.
I'm trying out Dir en grey and I kinda like them.
But I still have to look for more songs to get the conclusions because now I'm just a starter at Japanese male artists

Oh,and KaoriNeko,you are the one who promoted KAT-TUN's "HELL, NO" for me because of your sig
So I really thought the title "HELL, NO" was awesome so I found the song ad DL-ed it and I really liked it!
And you also made me start this thread because of that song,lol!
